Description
Technical field
The utility model relates to a kind of seam flange experiment on fatigue properties tooling, particularly relates to one kind and be related to and car tail
In gas after-treatment system, the relevant Work fixture device of the test of weld fatigue intensity between flange plate and pipe fitting is verified, is belonged to
Exhaust system experimental test technical field.
Background technique
For exhaust system, the position of various weld seams is often key position more weak in system, is welded in assembly
When, it often inevitably will appear welding defect, welded stress etc. in position while welding；The defects of solder skip, rosin joint, is often
Commissure is caused to become position more weak in system, temperature constantly changes in exhaust system in addition, it is easy in commissure
The Problem of Failure such as cracking are generated, flange-tube welding structure is welding structure extremely common in exhaust system, often uses this
A whole set of exhaust system is divided into multiple portions with convenient for assembly and replacement by kind structure；Fatigue behaviour at flange-pipe weld
It is very big to exhaust system entirety Influence of Fatigue Properties, it needs to combine vehicle roadway sign in product design Qualify Phase, to weakness
Position carries out fatigue test to verify whether design scheme can satisfy the durable requirement of vehicle.But no this item on the market at present
The universal tooling of test.
Summary of the invention
The purpose of this utility model is to provide a kind of flange welding fatigue property test toolings, realize method using tooling
Orchid-pipe weld experiment on fatigue properties, and fatique testing at elevated temperature can be realized by heating gun.
According to technical solution provided by the utility model: a kind of flange welding fatigue property test tooling, including tooling packet
Pedestal is included, flange mounting rail is detachably connected on pedestal, the location and installation being adapted to test sample is provided on flange mounting rail
Portion.
Tooling includes height adjustment device as a further improvement of the utility model,.
Height adjustment device includes column, track and pin as a further improvement of the utility model,；Flange mounting rail
Upper vertical direction is detachably connected column, and adjustment hole is provided on column, and track is vertically arranged on pedestal, be provided on track with
The compatible lock hole of column adjustment apertures, column can slide up and down in orbit, and column is relatively fixed by pin and track.
The portion of being located by connecting is U-type groove and bolt and nut as a further improvement of the utility model,.
Bolt slot is provided on pedestal as a further improvement of the utility model,.
Bolt slot is U-type groove as a further improvement of the utility model,.
Tooling further includes heating device as a further improvement of the utility model,.
Heating device is heater as a further improvement of the utility model,.

The time tested improves test efficiency.
Detailed description of the invention
Structural schematic diagram when Fig. 1 is utility model works.
Specific embodiment
Specific embodiment of the present utility model is further described with reference to the accompanying drawing.
In Fig. 1, including pedestal 1, track 2, column 3, flange mounting rail 4, pin 5, bolt of lower base 6, test sample 7, plus
Hot rifle 8, shake bar 9.
As shown in Figure 1, the utility model is a kind of flange welding fatigue property test tooling, including pedestal 1, on pedestal 1
It is provided with U-bolt slot, pedestal 1 is locked on workbench with bolt of lower base 6.Pedestal 1 is connected by height adjustment device
Flange mounting rail 4, height adjustment device are used to adjust height of the flange mounting rail 4 relative to pedestal 1, in being somebody's turn to do for the utility model
Height adjustment device includes column 3, track 2 and pin 5 in embodiment；Track 2 is vertically set on pedestal 1, flange mounting rail 4
Upper vertical direction is bolted column 3, and column 3 can slide up and down in track 2, is provided with adjustment hole on column 3, on track 2
It is provided with lock hole compatible with 3 adjustment apertures of column, column 3 is relatively fixed by pin 5 and track 2.It is practical new at this
In the other embodiments of type, height adjustment device is also possible to bolt and is vertically set on pedestal 1, vertical on flange mounting rail 4
Direction is detachably connected nut, and height of the flange mounting rail 4 relative to pedestal 1 is adjusted by the rotatable engagement of nut and screw rod
Degree.It is provided on flange mounting rail 4 and the U-shaped locating slot that bolt is adapted to is installed with test sample 7.When the flange plate of test sample 7
When for special-shaped flange plate, flange mounting rail 4 may customize to be adapted to.Tooling further includes heating gun 8, and heating gun 8 is mounted on pedestal 1
On same workbench, heating gun 8 makes test sample temperature reach test request.
The course of work of the utility model is as follows: using bolt of lower base 6 first, pedestal 1 is secured entirely on workbench.
Then the U-type groove on the flange two sides bolt hole of test sample 7 and flange mounting rail 4 need to be guaranteed that two bolts are relatively whole to it
Body is substantially symmetrical about its central axis, with tooling stress balance when guarantee test, is then fixed with bolt and nut.
Secondly by adjusting, pin 5 is opposite with pedestal 1 to adjust test sample 7 in the lead to the hole site of column 3 and track 2
Highly.It chooses whether to lead to hot gas using heating gun again according to experimental condition and adjusts shake bar 9 to 7 free end of test sample
Face, after inspection is errorless, starting fatigue test device drives shake bar to start to vibrate up and down, amplitude 0.8mm-1mm, and is tested
The record of data.
